A library for cartridges of a data storage tape comprises a drive with a cartridge
pocket and a magazine revolving about the drive with a plurality of receivers for
the cartridges. The receivers are positionable in front of a cartridge pocket in
order to change a cartridge between the receiver and the cartridge pocket. Cartridges
can be inserted or removed through a port of the housing of the library into the
receiver of the magazine. The cartridge pocket, a receiver positioned in front
of the cartridge pocket, and the port of the housing may be linearly aligned such
that cartridges can also be inserted through the port directly into the cartridge
pocket or can be removed directly from the cartridge pocket through the port.
